About the DLC:
The first DLC is BioShock Infinite: Clash in the Clouds. An add-on pack that puts an intense focus on BioShock Infinite® combat. Combine weapons, Vigors, Gear, Tears and Sky-Lines in ways you never thought possible as you square off against impossible odds. This pack features 60 challenges in 4 brand-new maps. Complete Blue Ribbon Challenges and unlock concept art, Voxophones, Kinetoscopes, and more in The Columbian Archeological Society.

The second is BioShock Infinite: Burial at Sea. A two-part add-on campaign featuring an all-new story for Booker and Elizabeth, set in the underwater city of Rapture before its fall.

These two campaigns will be available individually for $15.00 or 1200 Microsoft Points, and are also included as part of the BioShock Infinite Season Pass.

“We are really excited to offer our fans the content that they have been asking for,” said Ken Levine, creative director of Irrational Games. “With Clash in the Clouds, people get a pure action experience that takes BioShock Infinite combat to its highest challenge and intensity level. With the Burial at Sea episodes, we are building a Rapture-based narrative experience that is almost entirely built from scratch.”

The BioShock Infinite Season Pass is available now for $19.99 or 1600 Microsoft Points and includes all three pieces of add-on content, as well as the Early Bird Special Pack, which includes powerful weapon upgrades, exclusive gold weapon skins and infusion bottles to upgrade abilities.
